PhD CASE Studentship on ARM architectural semantics
Applications are invited for a fully funded PhD CASE studentship at
the University of Cambridge Computer Laboratory, with industrial
sponsorship from ARM Ltd; here are more details .
Teaching
Research
My research aims to put the engineering of real-world computer
systems on solid foundations, developing techniques -both
mathematically rigorous and pragmatically useful-
to enable the
construction of systems that are better-understood, more robust, and
more secure.
To do this requires tightly integrated theoretical and practical
research, spanning a range of Computer Science.
This is, broadly, applied semantics: I work in
programming languages, networking, and security,
developing and using techniques from
semantics, type systems, automated reasoning, and concurrency theory.
